Edwards, who will continue to present the BBC's 'Ten O'Clock News', will also anchor the 5pm-6pm slot on BBC News 24 from April 10. He joins Emily Maitlis and Ben Brown as the programme's co-hosts.
The changes are part of the BBC's ongoing ratings battle with Sky News for the hotly contested 5pm-6pm slot. Edwards was chosen for his high journalistic calibre and popularity with UK television audiences.
Helen Boaden, BBC director of news, said: "Huw is an excellent and experienced journalist who brings enormous authority to BBC News. He has been a much-loved part of BBC One's family of presenters for several years and I'm delighted that he is now including News 24 in his portfolio."
Edwards, who joined the BBC as a news trainee in 1984, has been presenting the 'Ten O'Clock News' since January 2003. He said: "This is a dream combination for me. I get to rejoin News 24, which I helped launch back in 1997, and to keep on presenting the Ten, which is an enormous privilege."
BBC News 24 currently receives 5.7m viewers a week compared with Sky News's 4.2m.
